WEATHERFORD (CBSDFW.COM/AP) – A judge in Parker County set a $750,000 bond for the 17-year-old who has been accused of killing his mother and 15-year-old sister in October, then calling 911 and confessing. Jacob Ryan Evans appeared at a pretrial hearing Wednesday in the case.

The judge turned down the defense attorney’s request to drop a capital murder charge. The defense attorney argued that a capital murder charge in Texas requires a death penalty or life prison sentence. But recent Supreme Court rulings declared those punishments improper for 17-year-olds like Evans.

The teen’s attorney said that he would appeal the ruling.

Evans has been jailed since his October arrest, at his upscale home in Aledo, located about 20 miles west of Fort Worth. In his 911 call, Evans can be heard telling the operator that he is “evil.”
